Jada Pinkett Smith goes to the gym to keep "sane".
The 43-year-old actress - who is known for her good physique - also admitted she does regular exercise because she loves to be praised by her actor husband, Will, 46, for her efforts.
She said: "Well, I love when Will looks at me and says, 'You look so freaking good!' When my husband of almost 20 years can't take his eyes off of me? That's amazing.
"But the number one reason I go to the gym is because it keeps me sane. It gives me a place to exert energy, frustration, sadness, happiness, and joy. I don't go to the gym just to look good. I go because it also keeps my head straight."
Jada also revealed that she likes to follow a healthy eating plan but does enjoy the occasional splurge on junk food.
She shared: "Our bodies are our own unique universes. Personally, I like to eat carbs. Breakfast is oatmeal, a banana, and another piece of fruit like a grapefruit or an orange. Later I have soft-boiled eggs or an egg-white omelette with spinach or salad. I make sure to have a lot of greens and fruit in my diet."
When asked if she ever treats herself, she added to SHAPE magazine: "I have that figured out too. I can hit a pizza on Friday - I love pizza - and then I have two days to let it dissipate through my system, so that by the time I get back on set on Monday, you can't see that pizza underneath all of those tight dresses on Gotham."
